A competent, comfortable near-luxury sedan crippled by a genuinely troublesome first-gen 9-speed automatic — buy the V6 SH-AWD, avoid the early 4-cylinder cars, and budget for transmission drama.

Every documented failure, earliest first

Ordered by the mileage the problem typically appears. VERY HIGH confidence means it's tied to a documented NHTSA recall, and 2 of these are rated Critical.

0k–15k mi● Critical$0–$4,500VERY HIGH
9-speed automatic transmission harsh shifts, hesitation, drops to neutral (wire harness/TCM issue, recall-covered)
How to catch it: Confirm the transmission wire harness recall (TCM connector) and any transmission software updates have been performed before you buy — get the service history printed.
Source: documented (NHTSA recall)
20k–50k mi● Watch$300–$900MODERATE
Rough idle, hesitation, and stalling from fuel system/injector or throttle body carbon buildup on the 2.4L four-cylinder
How to catch it: Use top-tier gasoline and do a walnut-blast intake cleaning around 40k since it's a direct-injection engine prone to carbon buildup.
Source: multi-source pattern (AI synthesis)
30k–70k mi● Plan$1,500–$3,500MODERATE
Clear-coat/paint delamination around rear windshield, C-pillars, and roof — widespread factory paint defect
How to catch it: Inspect the rear windshield trim and C-pillars closely before buying; Acura has extended goodwill paint coverage in some regions so call a dealer with the VIN to check eligibility.
Source: multi-source pattern (AI synthesis)
60k–90k mi● Critical$2,000–$4,000MODERATE
9-speed transmission mechatronic/valve body wear causing shudder in 2nd-3rd gear and delayed reverse engagement
How to catch it: Change transmission fluid every 30k miles with genuine Honda ATF-DW1 instead of the extended factory interval — this materially slows wear.
Source: multi-source pattern (AI synthesis)
70k–100k mi● Plan$0–$1,300MODERATE
V6 fuel pump failure (Takata-era Denso pump, subject to separate fuel pump recall) causing stalling
How to catch it: Run the VIN on NHTSA.gov for open recalls immediately — this fuel pump recall is a free fix if not already done.
Source: multi-source pattern (AI synthesis)
80k–120k mi● Watch$600–$1,200MODERATE
Front strut mounts and control arm bushings wearing, causing clunks over bumps
How to catch it: Have a shop inspect front end bushings at any pre-purchase inspection — it's a common but cheap fix if caught early.
